How to figure out the logs

[2ndAcr]

Been getting hit with huge lag lately. And we are trying to sort it out. Some days with exact battle things run smooth as can be, other days it is horrible.

I have been trying to figure out how to read the logs so I can help figure it out. Can someone decipher the following for me, I know it is obvious, but I want to make sure it is what I am thinking.

14772263,GOODFRAME,18,0,18321,18319,2,0:735 2nd Cavalry
14772263,SENDFRAME,18321
14772263,HAVEFRAME,16,0,18319,18319,1,0:John_VW
14772263,HAVEFRAME,17,0,18320,18319,1,0:John_VW
14772263,GOODFRAME,18,0,18321,18319,1,0:John_VW
14772263,LOWFRAME,16,0,18318,18319,1,0:John_VW
14772263,HAVEFRAME,16,0,18319,18319,3,0:735 Harry Cassidy
14772263,HAVEFRAME,17,0,18320,18319,3,0:735 Harry Cassidy
14772263,GOODFRAME,18,0,18321,18319,3,0:735 Harry Cassidy
14772263,LOWFRAME,16,0,18318,18319,3,0:735 Harry Cassidy
14772263,GOODFRAME,16,0,18319,18319,0,0:chijohnaok1
14772263,LOWFRAME,16,0,18316,18319,0,0:chijohnaok1
14772263,LOWFRAME,16,0,18317,18319,0,0:chijohnaok1
14772263,LOWFRAME,16,0,18318,18319,0,0:chijohnaok1

I am not sure what HaveFrame means, I can figure out the good and low.
